Abstract. Nickel belongs to the transition metal family and shows close chemical similarities with Fe and Co. Even more than these elements, it is concentrated in silicated Fe-Mg minerals by octahedral substitution with Fe 2+ ions. Thus, the mean mineral/ matrix partition coefficient of Ni is 14.0,5.0 and 2.6 for basaltic whole rocks, for olivine, and orthopyroxene and clinopyroxene, respectively.
